The fate of "small" open source

Is there any upside to opensourcing anything anymore? Anything published today becomes training data for the next model, with no attribution to the original work.

If the goal is to experiment, share ideas, or let others learn from the work, maybe the better default now is "source available", instead of FOSS in the classic sense. It gives people visibility while setting clearer boundaries on how the work can be used.

I learned most of what I know thanks to FOSS projects so I'm still on the fence on this.

Microsoft already did this for all code in every public repo.
